Black holes can split in two — but only if they spin at extreme speeds
Black holes can split in two — but only if they spin at extreme speeds

Scientists have long known that when two black holes collide, they merge to create a more massive black hole. New research suggests that the opposite may happen too: single black holes may split in two.

What looks like a neon pink treble clef floating out in space is actually a bizarre source of radio waves spotted deep in the cosmos.

NASA’s Chandra Breaks Down ‘Treble Clef’s’ Galaxy Cluster Collision
NASA’s Chandra Breaks Down ‘Treble Clef’s’ Galaxy Cluster Collision

Astronomers have used NASA’s Chandra X-ray Observatory to break down the cause of a remarkable formation of radio waves they have nicknamed the “Treble Clef” because its distinct shape strongly resembles the musical symbol. The researchers discovered the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision […]

Astronomers witness supermassive black hole gorge on a cosmic meal before ‘burping’ radio jets 300 days later

Using the NASA spacecraft Swift, astronomers observed a supermassive black hole burping radio jets 300 days after a heavy cosmic meal.

Astronomers detect most distant supermassive black hole-powered blazar ever: a cosmic beacon from the dawn of time
Astronomers detect most distant supermassive black hole-powered blazar ever: a cosmic beacon from the dawn of time

Astronomers have discovered the most distant and earliest blazar, an erupting supermassive black hole aiming its plasma jets directly at Earth.
